Research Project: Enhance Variety Development of Scab Resistant Hard Winter Wheat Varieties in Nebraska

Location: National Programs

Project Number: 0500-00053-003-71-G
Project Type: Grant

Start Date: May 3, 2014
End Date: May 2, 2018

Breeding for scab resistance with specific emphasis on reducing the level of DON to acceptable levels in our milling and baking industry for flour and whole grain products.

1. Use our scab mist nurseries to identify lines with improved scab tolerance and reduced DON with: a) native resistance (e.g. Overland, Lyman, Everest, Art, SY Wolf, Hitch, and new experimental lines), b) known major Fhb tolerance QTLs (e.g. the Wesley and Overland Fhb1 isolines, the Bakhsh Fhb1 lines, the soon to be developed doubled haploid lines with Fhb1, and other new lines from our breeding program, etc.), 2. Use designed crosses and molecular markers to introgress and pyramid known QTLs (Fhb1, Fhb3, 5As, etc.) in native resistance backgrounds, and 3. Advance lines through a full range of agronomic, scab and other disease, winter hardiness, and end-use quality tests. We will continue to improve our scab screening capabilities and to screen our preliminary (300 lines), intermediate (60 lines) and elite nurseries (60 lines) in replicated FHB screens, as well as, the lines in the collaborative scab evaluation trials. DON is measured on all the advanced and elite trials.
